Abstract
The paper introduces the working principle of frequency control permanent magnet synchronous motor,as well as the successful case of that the original fan drive de-vice was replaced with frequency control permanent magnet synchronous motor direct-drive fan in machinery ventilation cooling tower of Meisteel.Compared with the traditional cooling tower fan drive system,frequency control permanent magnet synchronous motor direct-drive cooling tower fan has the advantages of high transmission efficiency,simple structure,energy saving and environmental protection,less faults,etc.,the application prospect is broad.关键词
